ANGLE-GAGE ATTACHMENT FOR PAPER-CUTTING MACHINES.

To all whom it may concern:

Be it known that I HERMAN STENGEL, a citizen of the United states, residing at Los Los Angeles and State of California, have invented new and useful Improvements in Angle Gage Attaohments for Paper Cutting Machines, of which the following is a specification.

My object is to make an angle gage attachment for paper cutting machines, and my invention consists of the novel features herein shown, described and claimed.

Figure 1 is a front elevation of a paper cutting machine provided With an angle gage attachment in accordance with the principles of my invention, the view being taken looking in the direction indicated by the arrow 1 in Fig. 2.

Fig. 2 is an enlarged horizontal sectional detail on the line 2-2 of Fig. 1 and looking downwardly as indicated'by the arrows. Fig. 3 is a side elevation of the angle gage removed from the paper cutter, the view being taken looking in the direction indicated by the arrows 3 in Figs. 1 and 2.

The paper cutter has a straight back gage 1 provided with a plurality of vertical ribs 2, and the front faces 3 of the ribs 2 are finished to make the straight back gage against which a pile of paper is placed to make a straightcut. The cutting table 4 extends forwardly from the back gage 1 and when it is desired to cut paper at an gles other than right angles myangle gage attachment is applied to the back gage 1 and extends forwardly upon the cutting .40 8 extending from the back edges, each notch table 4.

The attaching blocks 5 and 6 are U-shaped in plan and the attaching blocks fit upon the cutting table 4 and have notches 7 and being adapted. to receive a rib 2. Set screws 9 and 10 are tapped through one arm of each block to engage the rib 2 and hold the block rigidly in place. The attaching block 11 is H-shaped in plan and has a notch 12 extendin from its back edge to receive a rib 2. et screws 13 and 14 are tapped throu 'h the rear arms of the block 11 to,

engage the rib 2,'so that the block 11 may be shifted laterally by loosening one screw and tightening the other.

The front arms 15 and 16 of the block 11 are horizontally bifurcated and pivot pins and 26 Specification of Letters Patent. Patented 11111629, 1920.

17 and 18 are mounted vertically through the bifurcated portions. The angle gage plates 19 and 20 have ears 21 and 22 fitting in the bifurcations of the arms 15: and 16 and the pivot pins 17 and 18 extend through theears 21' and 22. a

The angle gage plates'19 and. 20 have finished faces 23 and 24 to receive the block of paper. outwardly from the lower parts of theangle gage plates 19 and 20and rest upon the cutting table 4., The links 27 and 28 are pivotally connected to the base plates 25 by cap screws 29 and 30. The links Base plates 25 and 26 extend 27 and 28 are curved inplan and have longitudinally extending slots 31 and 32 in their outer halves, and the outer ends of the links 27 and 28 rest upon the attaching blocks 5 and 6. 2

Wing head cap screws 33 and 34 are inserted downwardly through washers 35 and 36 and through the slots 31 and 32 and tapped into the attaching blocks 5 and 6, so

that by loosening the screws the gage plates 19 and 20 maybe moved to bring the faces 23 and 24 into any desired angles relative to each other and relative to the back gage face 3 or the knife, and then by tightening the screws 33 and 34 the angle gage plates 19 and 20 will be rigidly held while the block of paper'is placed against the faces 23 and 24 and cut.

Obviously the cut of the knife upon the block of paper will be in a line at acute angles to the faces of the paper engaging the faces 23 and 24. By. manipulating the angle gage plates 19 and 20 the paper may be cut to any desired triangular form.

Thus I have produced an angle gage attachment for paper cutting machines having a straight back gage including vertical ribs; the attachment comprising outer attaching blocks having notches adapted to receive the ribs, set screws in the outer attaching blocks to engage the ribs, a central attaching block having a notch to receive a rib, set screws in the central attaching block to engage opposite sides of the rib, angle gage plates pivotally connected to the central attaching block, links pivotally connected to the angle gage plates and bearing upon the outer at-' taching blocks and having longitudinally extending slots, and cap screws inserted through the slots and tapped into the outer claimed.

I claim 1 ,Anangle gage attachment for paper cutting machines having a straight back gage including vertical ribs; the attachment comprising outer attaching blocks having notches adapted to receive the ribs, .set

screws in they outer attaching blocks to engage the ribs, a central attaching block having a notch to receive a rib, set screws in the central attaching blockto engage opposite sides of the rib, angle gage plates pivotally connected to the central attaching block, links pivotally connected to the angle gage plates and bearing upon the outer attaching blocks and having longitudinally extending slots, and cap screws inserted through the slots and tapped into the outer attaching blocks; so that by manipulatingthe cap screws the angle gage plates may be adjusted.

2. An angle gage attachment for paper cutting machines comprising outer attaching blocksmeans for detachably connecting said blocks to the back gage of a paper cutter, a central attaching block meansfordetachabl connecting said blockto the back gage o the paper cutter, angle gage plates pivotally connected to thecentral attaching block, and means for adjustably connecting blocks.

3. An'angle gage attachment for paper cutting machines, including outer attaching blocks, means for attachingsaid blocks to.

the back gage of a paper cutter, a central attaching block, means for connecting said block to the back gage of the paper cutter,

the angle gage plates to the outer attaching angle gageplates pivotally connected to .the

central attaching block, links pivotally connected at one end to said angle gage plates respectively, each of said linksbeing provided with a slot, and aclamp screw extending through the slot in each link and'engag
